How do I find the factors or divisors of the number 21,000,404?

Unfortunately, there's not simple formula to identifying all of the factors of a number and it can be a tedious process when trying to identify the factors of larger numbers. To find the factors of the number 21,000,404, it is easiest to start from the outside in. Here's what we mean:

Outside in Factoring

We start by creating a table and writing 1 on the left side and then the number we're trying to find the factors for on the right side in a table.

1 21,000,404

Next, we take the number 21,000,404 and divide it by 2.

In this case, 21,000,404 ÷ 2 = 10,500,202

If the quotient is a whole number, then 2 and 10,500,202 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

1 2 10,500,202 21,000,404

Now, we try dividing 21,000,404 by 3.

21,000,404 ÷ 3 = 7,000,134.6667

If the quotient is a whole number, then 3 and 7,000,134.6667 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

Here is what our table should look like at this step:

1 2 10,500,202 21,000,404

Let's try dividing by 4.

21,000,404 ÷ 4 = 5,250,101

If the quotient is a whole number, then 4 and 5,250,101 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

Here is what our table should look like at this step:

1 2 4 5,250,101 10,500,202 21,000,404

We keep dividing by the next largest number, in this case the number 5. If the quotient of 21,000,404 ÷ 5 is a whole number, then 5 and your quotient are factors of the number.


Keep dividing by the next highest number until you cannot divide anymore.


What you will end up with is this table:

1241,1872,3744,4234,7488,84617,6925,250,10110,500,20221,000,404

All of the numbers in the table above can be evenly divided into the number 21,000,404.

Finally, for your reference, here are all of the divisor combinations of the number 21,000,404:

1 x 21000404
2 x 10500202
